The diversity of birds around Green Lake came as a pleasant surprise. I had already been visited regularly by a northern raven, followed a squirt of song to a winter wren, flushed a turkey, listened to a wood thrush fluting deep in the forest, and lay in the dark listening to the distant hoot of a barred owl. At one point, a very large bird of prey flew noisily overhead, clutching something in its talons. I caught only a glimpse of the bird, through the trees and silhouetted against the bright sky, but it looked like an osprey (though there are no osprey nests on the lake).
After a late breakfast of corned beef hash, I took to the canoe and fished until 4:30 PM, trying everything: trolling deep down the center of the lake; nymphing toward and away from the shoreline; casting a streamer into the lakeshore structure; trolling a streamer along the shoreline at the drop-off line. Only one fish took my fly: an overly optimistic sunfish, which tried to take a streamer almost as long as itself.
I pointed my canoe back toward camp when thunder began to mutter in the distance. When the threatening storm seemed to hold off, I stayed in the canoe just offshore from my campsite, drifting a brassie on a strike indicator at various depths, and then casting a small nymph well-coated with float-em, in the hope that it might act like an emerger. Very slowly the thunder came closer. At 6 PM, the clouds dropped over the peak of the hill, hanging there like spider webs. I paddled to shore and made supper under my shelter. Just before 7 PM, a small but intense thunderstorm finally rolled overhead. I retired to the car to drink my coffee, eat cookies, and write a bit.
Several times during the day, I had come close enough to an emerging mayfly to watch the process. The mayfly lies on the surface, caught in the surface tension, with its head arched above the surface, and the "shuck" just below. The fly pulls free of the shuck in 15 - 30 seconds, then sits atop the surface film for another 10 - 15 seconds while its wings unfold properly. Then it lifts into the air.
I wish that could adequately describe how night came on. After the first storm had passed, I walked to the point about 30 m from my camp, hoping for a sight of the beaver as it emerged for the night. More thunder rumbled faintly. The mist hung over the lake, sagging sometimes to shroud the tops of the trees.
Slowly the trees merged into a dark band along the lakeshore. The sky remained lighter, with a dusty, blue hue. Both trees and sky reflected on the mirror-still water. A few raindrops pocked the glassy surface, then a few more. A gentle, steady shower developed. I stood in the shelter of a hemlock, snug up against the dry, rough bark. Across the lake, against the hill, a ribbon of mist seemed to sink lower, and a minute later, a curtain of heavier rain hissed over the water.
For five minutes, the rain dinted the surface of the lake, raising droplets in reply, so that the lake surface seemed alive. Darker swirls appeared on the water: only the wind whirling in small downdrafts, but the shadows seemed to lurk and move just under the surface, like spirits.
When the rain passed, the lake had grown too dark for photographs. Nearer, the trees still stood apart; across the lake, they rose in a solid silhouette, with the tallest pines blurring in the trailing mist. The beaver finally appeared, rounding the opposite point and passing about forty feet away. He move in and out of the darker reflections of the trees, silent and steadfast.
All along the far shore, the peepers now called, with a lone tree frog joining them. The thunder grew closer again, but the air had fallen utterly still. A bat flitted past over the water, seeming more a toy than something real, with a hint of silver in the wings and an unsteady, irregular rhythm. Now and then, the sky glowed briefly red from the approaching lightning.
The lake grew almost as dark as the trees. Little breezes began to shiver like ghosts over the surface. The thunder grew deeper, louder, longer, as the flashes behind the clouds changed from the dull orange of dying embers to the white heat of live coals.
I stayed in rapture on the lakeshore as long as I dared, thinking to myself that God has made places in the universe more spectacular, but surely not so sublime.
Finally, the lightning and thunder grew too close, and I become increasingly uncomfortable under the tall trees along the lakeshore. I left the dark lake to its watery spirits and retreated to the car -- beating the downpour by about 90 seconds. I watched the spectacle of the storm from the car, and when it passed, settled into my tent for the night.
